hello. Alaina here. So I was doing my advanced math homework last night and just wondering if any body knows how to do numbers 25 and 27 on page 5, and numbers 2 and 12 on page 16?

Number 25 asks A)to show that P(4,2) is equidistant from A(9,2) and B(1,6). and B) If (2,k) is equidistant from A and B, find the value of k.
27 says..P is a point on the x-axis 13 units from the point (-3,5). Find all the possible cooridnates for P.
numero dos..Write an equation of the like with slope 3/5 an dpassing through the origin. (I assume that "origin" means the coordinate (0,0)).
and finally, letter 12..It says, write an equation of the line through (-2,4) parallel to the line through (1,1) and (5,7).

These are the only four questions that I did not get on the homework. Any help is much appreciated.
